40 CFR Parts 60 and 63

Summary

On January 30, 2013, the Environmental Protection Agency (EPA) finalized amendments to the National Emission Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines and the Standards of Performance for Stationary Internal Combustion Engines. Subsequently, the EPA received three petitions for reconsideration of the final rule. On September 5, 2013, the EPA announced reconsideration of and requested public comment on three issues raised in the petitions for reconsideration. A summary of the public comments received on the September 5, 2013, notice of reconsideration and the EPA's responses to those comments (Response to Comment document) can be found in the rulemaking docket at Docket Number EPA-HQ-OAR-2008-0708. After careful consideration of the public comments received on the September 5, 2013, notice, the EPA has determined that it will not propose any changes to the regulations at this time related to the three petition issues, and is providing notice of this decision. The EPA is informing the petitioners of the decision in separate letters to the petitioners. The letters explain the EPA's reasons for not proposing changes to the regulations for those three issues. Further discussion of the three petition issues can be found in the Response to Comment document.

Effective Date: This final action is effective on August 15, 2014. Compliance Dates: For the revised SSM requirements and electronic reporting requirements for existing FPUF Production facilities is August 15, 2014. For the new requirements prohibiting the use of HAP ABAs for existing slabstock FPUF Production facilities is 90 days from the effective date of the promulgated standards, November 13, 2014. New sources must comply with all of the standards immediately upon the effective date of the standard, August 15, 2014, or upon startup, whichever is later.

40 CFR Part 63

Summary

This action finalizes the residual risk and technology review (RTR) conducted for the Flexible Polyurethane Foam (FPUF) Production source category regulated under national emission standards for hazardous air pollutants (NESHAP). In addition, the EPA is finalizing amendments to correct and clarify regulatory provisions related to emissions during periods of startup, shutdown and malfunction (SSM); add requirements for reporting of performance testing through the Electronic Reporting Tool (ERT); clarify the leak detection methods allowed for diisocyanate storage vessels at slabstock foam production facilities; and revise the rule to add a schedule for delay of leak repairs for valves and connectors.

40 CFR Part 63

Summary

The Environmental Protection Agency (EPA) is proposing amendments to the national emission standards for hazardous air pollutants (NESHAP) for off-site waste and recovery operations (OSWRO) to address the results of the residual risk and technology review (RTR) conducted under the Clean Air Act (CAA). In light of our residual risk and technology review, we are proposing to amend the requirements for leak detection and repair and the requirements for certain tanks. In addition, the EPA is proposing amendments to revise regulatory provisions pertaining to emissions during periods of startup, shutdown and malfunction; add requirements for electronic reporting of performance test results; revise the routine maintenance provisions; clarify provisions pertaining to open-ended valves and lines; add monitoring requirements for pressure relief devices; clarify provisions for some performance test methods and procedures; and make several minor clarifications and corrections.
